AIR-SCREEN FOR WINDOWS AND DOORS.

1 b all whom. it may concern:

Be it known that I, MCCLELLAN RUSAN, a citizen of the United States, residing at Ivlanitou Springs, in the county of El Paso and State of Colorado, have invented a new and useful Air-Screen for \Vindows and Doors, of which the following is a spec1fication.

This invention has for its object to provide novel means for preventing the ingress of insects and other foreign objects through windows and doors, and is embodied in certain novel arrangement and construction of parts as hereinafter described and as pointed out in the claims.

The invention is illustrated in the accompanying drawings, wherein similar reference characters indicate similar parts, and wherein Figure 1 is an elevation of an embodiment of the present invention. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a section on the line 33 of Fig. 1.

In carrying out the present invention there is employed a wooden frame F which comprises a pair of stiles and a rail connecting their upper ends, the frame being a three sided structure, in order that it may be applied over a door, although it is to be understood that a four sided structure may be employed in connection with windows, as will be apparent. The stiles and rails each embody a wooden or similar bar 5, which is designed for attachment to a window or door frame, and a cleat 6, of wood or similar material secured to the inner edge of and arranged at right angles to the bar 5. The free portion of the cleat 6 is beveled away from the bar 5, as clearly seen in Figs. 2 and 3.

Attached to the frame F, is an air chamber or tube C, which comprises a number of sections secured to the respective sections or parts of the frame. Each section of the air chamber or tube C is formed of a plate or strip of sheet metal, which is doubled and bent longitudinally to provide a flat back 12 resting against the respective bar 5, and having an angular portion 13 at one side resting against the bevel of the corresponding cleat 6, and a front 10 extending from the other side of the back to or toward the said angular portion 13, the front having an angular lip 14 cooperating with the free portion 1a of the angular portion 13 to form adischarge noz- Speeification of Letters Patent.

Serial No. 649,412.

zle. The cooperating portions 14L and 14 are doubled as at 15 and 15, the edges of the blank being bent back, and being secured together by means of rivets or other securing members 18. The blank is doubled between the back 12 and the front 10 to form a flange 11, which engages a grooved shoulder 8 formed on the bar The front 10 is curved in order that the lip 14: thereof may cooperate with the lip 14 of the angular portion 13.

Angular cars 16 are secured to the back of each section of the air chamber or tube, and project away from the elbow between the back and the angular portion 13, the ears 16 of each section of the chamber projecting between the bar and the cleat, and being secured to the edge of the bar, whereby each section of the chamber will be locked to the respective section of the frame, with the angular portion 13 and lips forming the nozzle, locked against the bevel of the cleat 6. The ears 16 are preferably secured to the bars 5 by means of nails or other securing members 9. The adjoining ends of the chamber sections are mitered together, as well as the sections of the frame, whereby a continuous nozzle N will be provided around the corners of the frame, the nozzle being coextensive with the frame.

One section of the air chamber is provided with a nipple 17, to which is connected a suitable air supply pipe 30, when the device is applied over a door or window, in order that air or other fluid may be supplied to the air chamber so as to be discharged from the nozzle N over the door or window open mg. It is evident that when the air is admitted into the chamber, the same will be discharged in a thin film or sheet from the nozzle N, the streams or films of air converging, so as to preclude the ingress of insects or other foreign objects through the window or door opening. A rod 20 is preferably secured to the nozzle portion of the upper section of the air chamber, and has a fly scare 21 of thin gauze hung therefrom, so that the air will raise and flap the fly scare to assist in scaring flies and other insects away from the door or window opening.

The present device is readily applied to a window or door frame, by attaching the bars 5 of the frame to the window or door frame, as will be apparent.

The present device permits an unobstructed opening, through which large objects may be conveniently passed, it being noted I that when the device is applied to a door frame there will be no obstruction to the passage of persons through the door.

The advantages of the present device over the ordinary meshed Wire screen, as 0rd naril) employed, will be apparent Without lengtlrv description.

lVhat is claimed as new is:

1, In a device of the character described, a frame embodying a bar. and a cleat secured to one edge of and arranged at right angles to the bar, the cleat being beveled HWUY from the bar; and an air tube embodying a back resting against the said bar and having an angular portion at one side resting against the said bevel of the eleat, and a front extending from the other side of the hack to the said angular portion and having an angular lip cooperating with said angrr lar portion to form a discharge nozzle, the back off the tube having means engaging be tween the bar and cleat.

2. In a device of the character described, a frame embodying a bar, and a cleat se t'lopies 01? this patent may be obtained for five cents each, by addressing the Commissioner oeaoao cured to one edge of and arranged at right angles to the bar, the cleat being beveled away from the bar; and an air tube formed of a sheetmetal blank doubled and bent longitudinally to form a flat hacl: resting against the said bar and having an angular portion at one side resting against the said bevel of the eleat and a curved :tront extending from the other side of the back to ward the said angular portion, and having an angular lip cooperating with the said angular portion to form a discharge nozzle, the blank being termed with a flange at the last mentioned side of the back, the said flange engaging the aforesaid bar, and the hack of the tube having means at the elbow between the back and the said angular portion engaging between the said bar and cleat.

In testimony that I claim the foregoing as my own, I have hereto a'tlixed my signature in the presence of two Witnesses.
